摘要： Methods for fabrication of leading edge shields and tapered magnetic poles with a tapered leading edge are provided. The leading edge shield may be formed by utilizing a CMP stop layer. The CMP stop layer may aid in preventing over polishing of the magnetic material. For the tapered magnetic poles with a tapered leading edge, a magnetic material is deposited on a planarized surface, a patterned resist material is formed, and exposed magnetic material is etched to form at least one tapered surface of the magnetic material.

摘要： Methods for fabrication of tapered magnetic poles with a non-magnetic front bump layer. A magnetic pole may have a tapered surface at or near an air bearing surface (ABS), wherein a thickness of the write pole increases in a direction away from the ABS. A non-magnetic front bump layer may be formed on the tapered surface of the magnetic pole and away from the ABS. The front bump layer may increase the separation distance between a shield layer and the magnetic pole near the tapered surface, thereby improving the performance of the write head.

摘要： A magnetic head for writing information on a relatively-moving medium has a pair of substantially flat soft magnetic pole layers separated by a pair of coil layers. A soft magnetic pedestal adjoins the leading pole layer adjacent to a medium-facing surface and is spaced from the second pole layer by a nanoscale nonferromagnetic gap, the pedestal having a layer of high magnetic saturation material that defines a throat height and extends beyond the throat height. A second high magnetic saturation material adjoins the trailing pole layer and either terminates at the throat height to form a second pedestal or extends to reach a magnetic backgap structure that magnetically couples the pole layers. The MR sensor can be located closer than the write transducer to the trailing end of the head to reduce separation between the read transducer and the write transducer.
